[net.arch] How did they really make the XT/370?

ptw@encore.UUCP (P. Tucker Withington) (02/12/85)

Here's another one of my "Whatever happened to...":

A while back there was talk that the XT/370 is based on a chip that IBM got
Motorola to make for them that was basically a 68000 with "new microcode".
I guess I can believe this, but are there any technical papers out there that
either confirm or "tell the whole story"?
